Quality Control

Our synthetic peptides are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation, to ensure compliance with research-grade specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, amino acid analysis, and other critical parameters. We support custom synthesis with specifications tailored to your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. For long-term storage, desiccate at -20°C. The product is hygroscopic (moisture-sensitive). Allow the vial to warm to room temperature in a desiccator before opening to prevent condensation and moisture absorption.
